The invention provides a fault detection system and a vehicle, and relates to the technical field of vehicles, the system is applied to a high-voltage interlocking loop with N detection connectors, the system comprises a controller, a decoder and N switch modules, the N detection connectors are sequentially connected in series, the N switch modules are electrically connected with the N detection connectors in a one-to-one correspondence mode, N is greater than or equal to 2, and N is greater than or equal to 1. The controller inputs a detection signal to each switch module and inputs a control signal to the decoder when determining that a fault detection connector exists in the N detection connectors, and the decoder controls each switch module to be switched on according to the control signal, so that each switch module inputs the detection signal to the detection connector connected with each switch module. And the controller judges whether the detection signal returned by the detection connector connected with each switch module is received or not so as to judge whether the detection connector connected with each switch module fails or not. According to the invention, the specific position of the fault can be accurately positioned under the condition that the high-voltage interlocking loop has the fault.
